Patented June 2, 1931 UNITED STATES SMOKING-PIPE Application filedAugust 27, 1928., SeriaI NoL 302,376.

This invention relates to improvements in smoking pipes. a

The primary object of the invention resides in a smoking pipe in whichthe smoke from the bowl is moderately cooled in its passage through thestem so as not to irritate the tongue and mouth of a smoker, and inwhich tobacco bits and moisture are trapped to prevent them fromentering the restricted bore of the stem and obstructing the freepassage of smoke therethrough.

Another object is to provide a smoking pipe in which tobacco bits andmoisture may be trapped, and after use, the same may be blown outthrough the bowl by ablast of air,

to keep the pipe in a clean dry condition.

A further object is the provision of a smoking pipe having a tubemounted in the stem thereof, the inner end of the tube being flared andwhich extends into a pocket having communication with the bowl, theflared end being disposed in spaced relation to cause the smoke to passthrough the pocket before entering the tube whereby tobacco bits drawnfrom the bowl into the pocket will accumulate in the latter.

With these and other objects in view, the

invention resides in certain novelconstruo tion and combinatlon andarrangement of parts, the essential features of which are hereinafterfully described, are particularly which V V Figure 1 is averticallongitudinal sectional view through my improved smoking pipe. kFigure 2is a detail perspective view of the tu e.

Referring to the drawings by reference characters, the numeral 10designates a smoking pipe which includes the usual bowl 11,-

stem 12, and mouthpiece or bit 13 which re movably fits into the stem.The outer end of the stem 12 is provided with an enlarged bore 1 1 whichcommunicates with pockets 15 of a reduced diameter in Figures 1 and 4into 1 The ducts 16 open which ducts 16 enter. into the bottom of thebowl and in Figures EN FFI JOSEPH 1*. Bosnia or JERSEY orrxnnw JERSEY 2and'3 they communicate direct with the bores 15 of the respective pipes.

The 'ool-' fits'into the bore 22 in the mouthpiece 13and is supported thereby. The intermediate portion of the tube issurrounded by an air space I by which the smoke passing through the tubeis moderately "cooled before passing to the outlet end of the pipe. Thetube, as shown in Figure 4, may be said to be floating as the majorportion of the length is free of any support.

In Figures '1, 2 and 5 of thedrawings, I'

lar serves as a support or bearing for the i flared end of the tube,while the opposite end bacco bits present therein is trapped inthepocket and the smoke allowed to pass into the tube in which it is cooled"before finally entering'the mouth of a smoker, After" a charge oftobacco has been smoked and the ashes emptied from the bowl,'the smokermay blow a blast of air through the vstem and by reason of the flaredend of the tube,

the blast of air will be deflected againstthe the pocket and bore toefiectiv'ely seal t h epocket from the bore to prevent theseeping ofmoisture between the joint which keeps the interior of the bore in a drycondition.
